What are the gametes for RrYy?
In P1 generation, the parent RRYY produces 2 gametes, RY and RY and parent rryy produces 2 gametes, ry and ry. Mendel observed that phenotypically, the F1 plants were with round yellow seeds. The genotype of these F1 hybrids was RrYy.

What is genotype of RrYy?
Organisms in this initial cross are called the parental, or P generation. The offspring of the RRYY x rryy cross, which is called the F1 generation, were all heterozygous plants with round, yellow seeds and the genotype RrYy.
What are the possible gametes This parent can make RrYy?
See if you can verify the following gamete lists for each genotype: RRYY gives RY gametes only RRYy gives RY and Ry gametes RrYY gives RY and rY gametes RrYy gives RY, Ry, rY, and ry gametes. Note that GAMETES NEVER HAVE DUPLICATE LETTERS. So gametes CANNOT look like Aa, or YY, or rr.
How many allele combinations are in RrYy?
Four possible combinations
Four possible combinations of the alleles for the two genes are possible- RY, Ry, rY and ry. 2. For the Punnett square of RrYy x RrYy, what phenotype ratio would be expected in the offspring?
How many gametes are produced by a pea plant whose genotype is RrYy?
Mendelian Genetics

|---|---|
| Organism that have two identical alleles for a particular trait are said to be? | Homozygous |
| A punnett square shows? | Probable outcomes of genetic crosses |
| How many different allele combinations would be found in the gametes produced by a pea plant whose genotype was RrYY? | Two |
What gametes can be produced by a parent with the genotype YyRr?
So, a YY genotype can only produce gametes with Y alleles. An individual with a Yy genotype produces half Y gametes and half y gametes. A yy genotype produces only y gametes. Example of a monohybrid cross….Mendelian genetics review.

What are male gametes?
They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome. These reproductive cells are produced through a type of cell division called meiosis.
What are gametes example?
In short a gamete is an egg cell (female gamete) or a sperm (male gamete). This is an example of anisogamy or heterogamy, the condition in which females and males produce gametes of different sizes (this is the case in humans; the human ovum has approximately 100,000 times the volume of a single human sperm cell).
When RrYy and RrYy are crossed in the F2 generation the ratio of RrYy RrYy & RrYy will be?
2 : 1 : 4 : 2.
What type of gametes will be formed by genotype RrYy?
A plant with genotype RrYy, produce four types of gametes during fertilization. They are RY, Ry, rY, ry. So, the correct option is ‘four’.
